    I am trying the acaswitchcpu command. When run without any arguments, it reboots fine into the CF card with the host CPU 68020.


    But when given the command 'nm' (acacpuswitch nm) , the computer tries to reboot but gets stuck at the very beginning, black screen. The only way out is a cold reset.


    The aca1233n is bone stock without any mod but an RTC module installed on the MB clockport.


    Any ideas?

    Switching back to 68030 requires a power cycle - that's a weakness of the hardware. It was planned to make it fully switchable, but there is no data path for the 68ec020 to reach the required registers of the accelerator.
